Remaining needle sleeve head forming machine

Abstract

The invention relates to a remaining needle sleeve head forming machine, belonging to the field of processing mechanical technology of medical equipment. The forming machine comprises a base, a clamp driving mechanism which is arranged on the base, a clamp sliding seat which is arranged on the clamp driving mechanism, a core rod clamp, a core rod arranged on the core rod clamp and a conical degree forming mechanism which is arranged on the base, corresponds to the core rod and is composed of a fixed base, a mold and a heating head. The forming machine is characterized in that: the forming machine also comprises a motor which is arranged on the clamp sliding seat, and the core rod clamp is fixedly arranged on the motor shaft of the motor and corresponds to the mold. The forming machine has the advantages that the forming effect is ensured and the passing percent is improved more than 98 percent, the forming efficiency is improved and the inspection working strength of the inspectors is reduced in the following inspection.

Description

technical field [0001] The invention belongs to the technical field of processing machinery for medical equipment, and in particular relates to a molding machine for the head of an indwelling needle sleeve. Background technique [0002] The indwelling needle is also used to be called a trocar, because the indwelling needle has good flexibility, long indwelling time in the vein and is not easy to break through the blood vessel wall, which is beneficial to reduce the pain caused by repeated punctures and protect the blood vessels. It also has the characteristics of being convenient for clinical medication, emergency rescue and reducing the workload of medical staff, especially nursing staff, so it has been widely used in clinical practice in recent years. [0003] As can be seen from the above description, the so-called indwelling needle is to send the cannula into the vein by the needle or needle body, and after the needle is removed, the cannula is left in the vein. The pro...

Problems solved by technology

[0004] The indwelling needle cannula head forming machine with the above structure is difficult to ensure the molding quality and the ideal pass rate when molding the indwelling needle cannula head, because it is difficult for the indwelling needle cannula head to be formed in a hot state after entering the mold 62. The mold cavity of the mold 62 fully removes the burrs left on the head during the processing of the cannula of the indwelling needle, and even if the burrs are removed, the taper effect of the head is poor, so it cannot be used clinically.

In order to ensure the effect of clinical use, the manufacturer can only strictly control the inspection, and manually inspect the formed indwelling needle cannula under a magnifying glass without any leakage. Moreover, the labor intensity of inspectors is high

On the other hand, due to the low pass rate, which is only about 50-60%, it causes serious waste, which not only causes resource loss, but also leads to increased production costs.
